286: Twenty Cans of Gas (Repeat)
Colin O'Flynn, CTO of NewAE Technology and an assistant professor, discusses his company's ChipWhisperer platform, which enables side-channel power analysis and fault injection attacks on embedded devices. He explains how differential power analysis recovers encryption keys by correlating power consumption with data bus activity, noting that while the technique is decades old, many IoT devices remain vulnerable. O'Flynn also covers FPGA design for precise timing, software countermeasures like masking, and the ethical implications of making security research tools accessible to both defenders and attackers.
